I like the taste and the fact that it does not have fluoride. But it contains carrageenan and sodium coco-sulfate. Carageenan is a somewhat controversial substance made from seaweed. There is some research out saying that it is upsetting to the GI track. They use it as an inexpensive thickener.
Sodium Coco Sulfate is just a highly, highly diluted form of Sodium laurel sulfate (SLS). If you're allergic to one, you're still allergic to the other.
This is a trick the industry is using. So saying it is SLS free is a bit deceptive. So be aware.
